In this optics activity, learners create flip books by drawing an image like an eye opening and closing on 24 small pages of paper.

In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.

Learners use compasses to detect the magnetic field created by current moving through a wire. This is one of four activities learners can complete related to PhysicsQuest 2008.

Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel.

In this activity, learners explore light and shadows by creating a lantern they can keep on their nightstand.

In this activity, learners create their own obstacle course based on Bernoulli's Principle and try to get a floating ball from the start of their course to the finish line.

In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.

Learners drop a magnet through a coil of wire to create electric current in a circuit. LEDs in the circuit allow learners to detect the direction of current flow.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp
